TEBAOFLEX TBPUR-RF 0.6/1 kV is a reinforced heavy-duty double-sheath polyurethane (PUR) round reeling cable engineered for spring-driven and motorized random-winding and monospiral cable drums on horizontally moving industrial machinery. Rated for horizontal travel speeds up to 90 m/min and specific tensile loading up to 20 N/mm² (350 N to 11,100 N), its compact RAL 6032 safety-green PUR outer jacket resists cable-on-cable drum friction, sharp yard aggregate, hydraulic oils, UV radiation, and coastal moisture.
1. Application Scope: Random-Winding vs. Monospiral Drum Reels
Selecting a reeling cable requires matching mechanical reinforcement to how the drum stores and guides the cable. TBPUR-RF 0.6/1 kV bridges the gap between standard 60 m/min shop reels and 180 m/min anti-torsion port gantry drums:
- Random-Winding (Scramble-Wound) Reels: Multi-layer drums on transfer cars, portal cranes, bulk stackers, and timber/steel-yard transporters where overlapping cable layers demand a slick, cut-resistant double-PUR wall and thermal derating review.
- Single-Layer Monospiral Reels: Narrow-flange spiral drums on rail-mounted gantries, bridge cranes, and automated handling vehicles requiring circular cross-section stability and controlled roller-guide entry.
| TEBAOFLEX PUR Reel Tier | Target Drum Duty | Max Horizontal Speed Ref. | Tensile Load Reference |
|---|---|---|---|
| TBPUR-SD (Standard Duty) | Light/medium spring & workshop reels | Up to 60 m/min | 12 N/mm² |
| TBPUR-RF (Reinforced Duty) | Heavy random-winding & monospiral drums | Up to 90 m/min | 20 N/mm² (size-specific table below) |
| TBPUR-HD / (N)SHTÖU-J | High-acceleration motorized port crane reels & S-bend sheaves | Up to 180–240 m/min | 25–30 N/mm² (anti-torsion braid) |
For multi-plane pulley routes or rubber reeling drums, compare our (N)SHTÖU-O / -J 0.6/1 kV rubber reeling cable, NTSFLCGEWOEU medium-voltage flat reeling cable, and port & crane reeling cable selection guide.


Operating Envelope & Safety-Turn Check: The published 90 m/min speed and tensile figures apply strictly to horizontal travel without uncontrolled deflection pulleys. Always retain at least 1–2 dead safety turns on the drum barrel before clamping, and consult TEBAOFLEX separately for level-wind spindles, vertical lift baskets, or continuous water immersion.
2. Cable Construction (Reinforced Double-PUR Architecture)
Both multicore 2.5 mm² control cables and 4G / 3+3 split-earth power feeders use a compact, torsion-resistant concentric build:
4G and 3+3) or black numbered control cores (7G2.5 to 39G2.5), each incorporating a Green/Yellow protective-earth conductor.25–185 mm² 3-phase sizes place 3 split earth cores symmetrically in the outer interstices.RAL 6032 signal green with surface marking TEBAOFLEX TBPUR-RF G mm² 0.6/1 kV.3.

5. Frequently Asked Engineering Questions
What reel types is TBPUR-RF 0.6/1 kV engineered to serve?
TBPUR-RF 0.6/1 kV is engineered specifically for horizontal spring-driven and motorized random-winding (multi-layer overlapping) reels and single-layer monospiral drums on transfer cars, portal cranes, bulk-handling machines, and industrial hoists traveling up to 90 m/min.
How does TBPUR-RF differ from standard-duty 60 m/min and high-speed 180 m/min reeling cables?
Standard-duty PUR drum cables (TBPUR-SD) typically target speeds up to 60 m/min and 12 N/mm² tensile stress. TBPUR-RF adds a reinforced core/double-PUR structure supporting up to 90 m/min horizontal travel and 20 N/mm² tensile capacity (up to 11,100 N on 3×185+3G35 mm²). Ultra-high-speed container crane gantries (120–180+ m/min or multi-sheave S-bends) require anti-torsion braided constructions such as TBPUR-HD or (N)SHTÖU-J.
What are the minimum bending radii on the reel spool, anti-tension drum, and guide roller?
Maintain a minimum inner bending radius of 6 × OD on the active winding spool barrel, 4 × OD on the dead-turn anti-tension anchor drum, and at least 9 × OD through any roller funnel or directional guiding device.
Why do 25 mm² to 185 mm² power sizes use a 3-phase + 3G split-earth layout?
Splitting the green/yellow protective conductor into three equal interstitial cores (e.g., 3×50 + 3G10 mm² or 3×185 + 3G35 mm²) fills the outer valleys between the three large phase cores, producing a smaller, truly circular cable diameter that winds smoothly onto monospiral flanges without flat-spot wedging.
Why must ampacity be derated on multi-layer random-winding cable reels?
Coiled layers left on a random-winding drum restrict convective cooling compared with unwound cable in free air or a ventilated monospiral spiral. Always supply your continuous motor current, duty cycle, ambient temperature, and maximum coiled layers on the drum so TEBAOFLEX can apply IEC/VDE drum-layer derating factors.
What system inputs are required to quote a TBPUR-RF 0.6/1 kV drum cable?
Provide reel arrangement (random-winding vs monospiral), spring or motor drive, core count and cross-section, operating voltage and current, active travel distance plus dead-turn length, travel speed, acceleration, minimum barrel/guide diameters, and ambient chemical or sub-zero conditions.
